Raman Spectroscopy

    I have read about it, and interested. Here's some questions not obvious in the references I read.

    For the strokes where the laser final result is higher than the ground state or more accurately described by Wikipedia "If the final vibrational state of the molecule is more energetic than the initial state, the emitted photon will be shifted to a lower frequency for the total energy of the system to remain balanced. This shift in frequency is designated as a Stokes shift."

    What are the ways you can further increase the vibrational state of the molecule so you get even bigger strokes shift? for example.. from wavenumber of 2000 to 8000 (meaning the frequency is less because the molecule is getting increases in the energy)? Does heating count as one? or using catalysts for example?

    Is the energy increase in the strokes (above ground state) related to the QM Hamiltonian (which handles all energy)?

    Who has handle Raman Spectroscope? How much is the cheapest system you can buy and accurate enough?
